SPECIFICATION forming part of Letters Patent No. 305,354, datedSeptember 16, 1 884.

Application filed March 9, 1882. (No model.)

To all whom it may concern:

. Be it known that I, ANDREW J. UPHAM, of

Sterling, in the county of W'hiteside and State of Illinois, haveinvented certain new and use ful Improvements in Barbed-Metal-StripFencing; and I do hereby declare that the following is a full,clear,andexact description of the same, reference being had to the accompanyingdrawings, forming a part of this specification, and in which- Figure 1represents a side view of a section of my improved barbed-metal-stripfencing. Fig. 2 represents an edge view of the section of fencing shownin Fig. 1; and Fig. 3 represents a section on line 00 m, Fig. 2, lookingin the direct-ion of the arrow of the same figure.

The natureof my invention consists in the combination,with aflat metalst-rip,of asheetmetal barb stamped or out out and attached thereto in apeculiar manner, to be hereinafter more fully described.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describeit more in detail.

In the drawings, the part A represents a section of a thin strip ofmetal, such as is suitable for making fences. The part B represents asheet-metal barb stamped or cut out of a strip of thin metallicmaterial. It is provided with two points, a a.

My improved barbed fencing is constructed in the following way: A slitor opening is made along the center line of the strip A at regularintervals,as shown at b,Figs. 1 and 3. Through this opening is insertedone end of the fiat metal barb B. Half the length of the barb is passedthrough the opening I), each end a a extending out in a straightdirection from the strip A. The part c is then bent or folded over I oneedge of the strip, and pressed down so as other side of the strip A, thetwo ends a a being left projecting out in opposite directions, as fullyshown in Figs. 1 and 3 of thedrawings. The barb B having been insertedor passed through the opening b, the parts 0 and (1 may be bent orfolded over at the same time and by one operation.

If preferred, in the manufacture of my improved fencing, mechanism maybeemployed so as to press one half of the strip A at the opening I) in onedirection, and the other half in an opposite direction, whereby one endof the barb B may be run through said opening or slit while resting uponthe side of one half of said strip, in which case the ends of the barbswould not have to be bent so far to bring them into the position shownin Fig. 3 as they would in the mode of manufacture first abovedescribed. In eitherof themodes above described the operation of bendingthe barb I ANDREYV J. UPHAM.
